Draw Sizer - Geometric ProgressionThis utility employs geometric progression to compute drawer face heights. With this technique, heights increase by a constant multiplicative factor, referred to as the common ratio.

Draw Sizer - Hambridge ProportioningThis utility employs the Hambridge proportioning technique to generate a smooth (some would even say "natural") progression of drawer heights that are in balance with the width of the drawer unit.

Footulator: Board Foot CalculatorHere is a bare-bones board foot calculator for tallying up lumber requirements. Just enter your desired thickness, width, length, and quantity and it will compute board feet and total board feet. Nice and simple.

Tabulator: Board Foot Calculator and Lumber TabulatorA board foot calculator, bill of materials generator and lumber tabulator all in one. The tabulator can help you tally up your lumber requirements for your next project and create a professional-looking lumber materials list. It computes board feet by species, total board feet, cost by species, and total cost - with provision for an optional waste factor. It can also accomodate resawing, a feature not generally found in your run of the mill board foot calculators.

The Sagulator - Shelf Sag CalculatorThe Sagulator helps you design shelves by calculating shelf sag (deflection) given type of shelf material, shelf load, load distribution, dimensions, and method of attachment. You can also specify an edging strip to further stiffen the shelf.

The ShrinkulatorA wood shrinkage and expansion calculator. The Shrinkulator helps you estimate dimensional changes in wood, either shrinkage or expansion, based on changes in the wood's moisture content.
